QoS Based Clustering for Vehicular Networks in Smart Cities

Today, Vehicular Ad Hoc Network (VANET) is one of the most important smart city system components. VANETs are distinguished by their high mobility, high information storage capacity, available energy, and the environment governed by road infrastructure but there are still many challenges to be faced to achieve good communication between vehicles. In the traditional ad hoc mobile networks, these difficulties have often been overcome by a clustered topology. The clustering in VANETs can reduce the communication problems and makes the network appear smaller and more stable according to the view of each vehicle. In this work, we propose a VANET clustering solution called “QoSCluster”, which aims to maintain the cluster structure while respecting the quality of service requirements as the network involves. We simulate our protocol using the Veins platform, the OMNET simulator, and the realistic mobility model SUMO.
